Temporal dissipative Kerr solitons (DKSs) and their frequency counterparts, Kerr frequency combs (KFCs), have been extensively explored in the anomalous dispersion regime for both continuous wave (CW) and pulse-pumped microresonators. Compared to the CW pumping, the pulsed pump scheme has been shown to produce DKSs with higher robustness. Recently DKS states have also been explored in the normal dispersion regime as well. In this work, we demonstrate a stable single DKS state originating from a normal dispersion regime of a silicon nitride (Si3N4) racetrack microring resonator with a built-in spectral filter for a chirped super-Gaussian pulsed pump. Numerical simulations aided with analytically derived formulations indicate that a stable square-shaped chirped DKS with a broad KFC can be generated. The proposed scheme also enhances the stability of the single-chirped DKS state. The interplay of input chirp along with the spectral filtering effect causes the stable single DKS to be trapped conveniently to the center of the driving pulse background. We believe that the findings along with derived analytical formulations will be useful and might find applications in communication, spectroscopy, optical tweezers, and more general all-optical manipulation of light pulses.
